I found a way to change those 3 shortcuts, that acer did not alowed to remove/change them.
ok with a registry aditor go to
HKEY_LOCAL_MACHINE/software/Acer/shell/Homescreen
and will see some strings values like
ShortcutLinkPathx
then edit the ShortcutLinkPath1 (or 2 0r 3) and erase the adress of the shortcut.
now save changes, go to homescreen ans press edit!
you would be able to change them whatever you want!
